When Arsenal managed to qualify it meant they could not be underestimated, for whatever reason Bayern Munich also had to be careful, after all both teams could fight each other 50:50 both of them were equally strong. I will not take it lightly, that the conditions of each team are different and in the hands of different coaches too. For this reason the meeting between the two is not just about experience in the UCL anymore but a battle over which coach tactics are effective. I think Arsenal can still beat Bayern Munich and that has huge potential. Bayern Munich itself now relies on Kane or Sane, while Arsenal strength is more evenly distributed, the same as Manchester City. Each line of Arsenal players is quite solid.
Yes Arsenal have so far gone quite well in the league and also the Champions League but I think for now they have an opponent that has not been expected, after suffering many defeats to Bayern Munich, of course from the beginning of the escape they did not hope not to meet Bayern Munich again, because indeed they are aware that no matter what the condition of Bayern Munich in the league, Bayern Munich remains a very dangerous club in the Champions League so far.
I don't want to underestimate Arsenal, but so far we can see 90% of predictions from football experts in the media and social media actually assume that Arsenal will not be able to beat Bayern Munich even though they have a better performance at the moment in the league, what you say is quite true, if Arsenal's performance and strength have been evenly distributed on every line, but what you forget is the Arsenal squad which is mostly young players of course Just don't have the mentality and experience that Bayern Munich current squad has, that's why if you equate Arsenal with Manchester City then I would say you are wrong because at the moment Arsenal's level is still very far compared to Manchester City who have a lot of experience in winning domestic and European competitions.
